What Are Hurricanes Called in the Pacific?

We’ve all heard of hurricanes — massive spinning storms that can cause powerful winds, heavy rainfall, and storm surges. But did you know that hurricanes have different names depending on where they occur? If you’re wondering what they are called in the Pacific Ocean, let’s dive in step by step and make it clear.

Understanding Hurricanes

Before we get into names, let’s understand what a hurricane actually is. A hurricane is a type of tropical cyclone — a rotating storm system that forms over warm ocean waters. These storms are fueled by heat and moisture from the sea, causing towering clouds, heavy rain, and strong winds that spiral around a low-pressure center.

Tropical cyclones are classified differently based on their maximum wind speed:

  • Tropical Depression: Wind speeds less than 63 km/h (39 mph)
  • Tropical Storm: Wind speeds between 63 km/h and 118 km/h (39–73 mph)
  • Hurricane / Typhoon: Wind speeds above 119 km/h (74 mph and above)

Names Change Based on Location

Here’s the key point: tropical cyclones have different names depending on the ocean basin they form in. This is why the term hurricane might be correct for one ocean but not for another.

In the Pacific Ocean

In the Pacific, the name for hurricanes depends on which part of the ocean we’re talking about:

  • Eastern Pacific (near the Americas): They are still called hurricanes. For example, if a big storm forms off the coast of Mexico, it’s called a hurricane.
  • Western Pacific (near Asia): They are called typhoons. For instance, storms impacting the Philippines, Japan, or China have the “typhoon” label.

So, if you were in Hawaii or off the coast of Central America, you’d hear “hurricane.” But if you were in the Philippines or Japan, it would be called a “typhoon” — even though it’s the same kind of storm.

Why Different Names?

The difference in names is mainly historical and regional. Organizations like the World Meteorological Organization (WMO) coordinate naming conventions to make communication easier in local regions. In simple terms, the storm’s physics don’t change — only the name and regional terminology do.

Quick Reference for Naming Tropical Cyclones

  • Atlantic Ocean: Hurricane
  • Eastern Pacific (East of the International Date Line): Hurricane
  • Western Pacific (West of the International Date Line): Typhoon
  • Indian Ocean: Cyclone

Fun fact: South of the equator, in places like Australia and Madagascar, they’re often just called “cyclones,” but they’re still the same thing as hurricanes and typhoons.

Examples to Make It Clear

Let’s imagine you have two friends — one living in Mexico and another in the Philippines. If a massive tropical cyclone forms in each of their regions:

  • Mexico’s storm: Called Hurricane Rosa
  • Philippines’ storm: Called Typhoon Mangkhut

Both storms could have wind speeds of 150 km/h, heavy rain, and similar characteristics. The only real difference? The regional term used to describe them.

Key Characteristics Remain the Same

Regardless of the name, hurricanes, typhoons, and cyclones share the same features:

  • They form over warm ocean water (usually 26°C / 79°F or warmer).
  • They rotate due to Earth’s rotation — counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
  • They can cause severe flooding, wind damage, and dangerous storm surges.

Summary of What Hurricanes Are Called in the Pacific

To quickly sum it up:

  • Eastern Pacific: Hurricane
  • Western Pacific: Typhoon
  • Both are types of tropical cyclones with similar structures and dangers.

💡 Final Thought

Whether it’s called a hurricane in the Eastern Pacific or a typhoon in the Western Pacific, these powerful storms remind us of the incredible energy contained in our planet’s atmosphere. Names may change according to the region, but understanding their nature helps us stay informed and prepared. So next time you hear about a “Pacific typhoon” or an “Eastern Pacific hurricane,” you’ll know they’re simply regional names for the same awe-inspiring — and sometimes dangerous — tropical cyclone.
